One way to rename a file is to open the program that was used to create the file, open the file, and then save it with a different name. However, there's a quicker way:
Right-click the file that you want to rename, and then click Rename.
Type the new name, and then press Enter.
If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
If you can't rename a file, you might not have permission to change it. For more information, see What are permissions?
You can also rename several files at one time, which is useful for grouping related items. To do this, select the files, and then follow the steps above. Type one name, and then each of the files will be saved with the new name and a different sequential number at the end (for example, Renamed File (2), Renamed File (3), and so on).
